A 6.47 micro-coloumb particle moves through a region of space where an electric field of magnitude 1300 N/C points in the positive x direction, and a magnetic field of magnitude 1.33 T points in the positive z direction. If the net force acting on the particle is 6.27E^-3 N in the positive x direction> Required:
Calculate the magnitude of the particle's velocity. Assume the particle's velocity is in the xy plane.

v = 248.8 m/s

Explanation:

Given that,

Charge, q =

Electric field, E = 1300 N/C

Magnetic field, B =1.33 T

The force acting on the particle,

We need to find the magnitude of the particle's velocity. The net force on the particle is given by :

So, the magnitude of the particle's velocity is 248.8 m/s.
